[0017] After adopting the above structure, the spliced display screen bracket of the present invention has the following advantages compared with the prior art:

[0018] 1. The bracket body of the spliced display screen bracket adopts a square frame-shaped bracket body composed of two transversely arranged retractable beams and two longitudinally arranged retractable columns connected in sequence. When the beams and the columns are unfolded, the bracket body is in an unfolded state, and the bearing area of the bracket body is adjusted according to the unfolded length of the beams and the columns. When the bracket body is unfolded to an appropriate size, a connector or hook is installed on one of the side walls of the bracket body. The connector or hook can be used for installing and splicing multiple display screens. Therefore, the bracket body of the spliced display screen bracket can be adjusted in size according to user needs. When adjusting the size of the bracket body, the unfolded length of the beams can be adjusted separately, or the unfolded length of the columns can be adjusted separately, or the unfolded length of the beams and the columns can be adjusted simultaneously, so as to meet the splicing of different numbers of display screens and meet the needs of users; in addition, when the beams and the columns are in a closed state, the interior of the square frame formed by the bracket body can be used to accommodate the legs, so that the bracket body occupies less space when it is in the closed state, thereby saving packaging costs and facilitating transportation.

[0019] 2. The first crossbeam, the second crossbeam, the first column and the second column of the spliced display screen bracket are driven to expand or close by a linear drive mechanism, that is, when the first linear drive mechanism is energized, the first crossbeam and the second beam are driven to expand or close synchronously; when the second linear drive mechanism is energized, the first column and the second column are driven to expand or close synchronously; the expansion and closing of the bracket body can be automatically controlled. After purchasing the spliced display screen bracket, the user does not need to assemble it, but only needs to power on the first linear drive mechanism and / or the second linear drive mechanism to realize the expansion and closing of the bracket body. The operation is very convenient, labor-saving, and the user experience is good.

[0020] 3. The provision of the third column further improves the structural stability of the bracket body. When the first beam and the second beam are extended to a long length, the provision of the third column is not only used to support the first beam and the second beam to make the bracket body structure firm, but also the third column can be used to install connectors or hooks for display screen installation and splicing; the third column is driven by the third linear drive mechanism to expand or close synchronously with the first column and the second column.

[0021] 4. The first end of the third column is connected to the side wall of the first movable tube of the first beam away from the first fixed tube, and the second end of the third column is connected to the side wall of the first movable tube of the second beam away from the first fixed tube; when the bracket body is in a folded state, the third column is close to the second column; the connection between the third column and the first beam and the second beam does not affect the expansion or folding of the first beam and the second beam, and when the bracket body is in a folded state, the third column is close to the second column; this makes the volume of the bracket body smaller after folding, saving packaging costs.

[0022] 5. A wireless receiving module can be installed on the controllers of the drive motors of the first linear drive mechanism, the second linear drive mechanism, and the third linear drive mechanism. The wireless receiving module is wirelessly connected to a mobile phone or a remote control, and the user can use the mobile phone or the remote control to expand or close the bracket.

[0029] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown;

[0031] The present invention relates to a splicing display screen bracket, which includes a bracket body 1 and a support leg 2. The bracket body 1 is used for installing and splicing a display screen 6, and the support leg 2 is detachably connected to the bottom of the bracket body 1; a connector or hook can be installed on one side of the bracket body 1, and the connector or hook is used for installing and splicing the display screen. The connector or hook is a product with a relatively mature structure in the prior art. For details, please refer to the patent that the applicant of this case has applied for and disclosed, the authorization publication number of the patent is CN103807577B, and the name is a patent application for a mobile splicing screen bracket. The patent application discloses a hook for connecting splicing display screens, which can be installed on the beam or column of the present invention for use. The detailed structure of the hook is not described in detail without the invention; the bracket body The body 1 includes two transversely arranged retractable beams 3: a first beam 300 and a second beam 301, and the first beam 300 and the second beam 301 can be synchronously expanded or closed along their length directions; two longitudinally arranged retractable columns 4: a first column 400 and a second column 401, and the first column 400 and the second column 401 can be synchronously expanded or closed along their length directions; the two beams 3 are arranged between the two columns 4, and the two ends of the first beam 300 are respectively connected to the first ends of the first column 400 and the second column 401, and the two ends of the second beam 301 are respectively connected to the second ends of the first column 400 and the second column 401, and the first beam 300, the second beam 301, the first column 400 and the second column 401 are connected to the second ends of the first column 400 and the second column 401, and the first beam 300, the second beam 301, the first column 400 and the second column 401 are connected to form a square frame-shaped bracket body. The bracket body of the spliced display screen bracket adopts a square frame-shaped bracket body composed of two transversely arranged retractable beams and two longitudinally arranged retractable columns connected in sequence. When the beams and the columns are unfolded, the bracket body is in an unfolded state, and the bearing area of the bracket body is adjusted according to the unfolded length of the beams and the columns. When the bracket body is unfolded to an appropriate size, a connector or hook is installed on one of the side walls of the bracket body. The connector or hook can be used for installing and splicing multiple display screens. Therefore, the bracket body of the spliced display screen bracket can be adjusted in size according to user needs. When adjusting the size of the bracket body, the unfolded length of the beams can be adjusted separately, or the unfolded length of the columns can be adjusted separately, or the unfolded length of the beams and the columns can be adjusted simultaneously, so as to meet the splicing of different numbers of display screens and meet user needs; in addition, when the beams and the columns are in a closed state, the interior of the square frame formed by the bracket body can be used to accommodate the supporting legs, so that the bracket body occupies less space when it is in a closed state.

[0032] The first crossbeam 300 and the second crossbeam 301 both include a first fixed tube 302 and at least one first movable tube 303 that slides on the first fixed tube 302, and the first crossbeam 300 and the second crossbeam 301 are both provided with a first linear drive mechanism, which is used to drive the first movable tube 303 to slide relative to the first fixed tube 302, so that the first crossbeam 300 and the second crossbeam 301 are expanded or closed along their length direction.

[0033] For example Figure 2 As shown, each of the first and second columns 400, 401 includes a second fixed tube 402 and at least one second movable tube 403 that slidably engages the second fixed tube 402. Furthermore, each of the first and second columns 400, 401 is provided with a second linear drive mechanism that drives the second movable tube 403 to slide relative to the second fixed tube 402, thereby expanding or contracting the first and second columns 400, 401 along their lengths. The first and second beams, as well as the first and second columns of the spliced display stand, are all driven to expand or contract by the linear drive mechanism. Specifically, when the first linear drive mechanism is energized, the first and second beams are synchronously expanded or contracted; when the second linear drive mechanism is energized, the first and second columns are synchronously expanded or contracted. The expansion and contraction of the stand body are both automatically controlled. After purchasing the spliced display stand, users only need to activate the first and / or second linear drive mechanisms to expand and contract the stand body, eliminating the need for assembly. This makes operation very convenient.

[0034] Between the first column 400 and the second column 401, there are third columns 5 with the same number as the first movable tubes 303 of the beam 3. The third columns 5 are parallel to the first column 400 or the second column 401, and the shape and structure of the third columns 5 are the same as the shape and structure of the first column 400 or the second column 401. Each third column 5 includes a third fixed tube 500 and at least one third movable tube 501 slidingly fitted on the third fixed tube 500; each third column 5 is provided with a third linear drive mechanism, and the third linear drive mechanism is used to drive the third column 5 to expand or close along its length direction; the two ends of the third column 5 are respectively connected to the first beam 300 and the second beam 301, and the third column 5 is synchronously expanded or closed with the first column 400 and the second column 401. The provision of the third column further improves the structural stability of the bracket body. When the first beam and the second beam are relatively long when unfolded, the provision of the third column is not only used to support the first beam and the second beam to make the bracket body structure firm, but also the third column can be used to install connectors or hooks for installing and splicing display screens; the third column is driven by the third linear drive mechanism to expand or close synchronously with the first column and the second column.

For example, the crossbeam 3 includes a first movable tube 303, and the third column 5 is single. The first end of the third column 5 is connected to the first fixed tube 302 of the first crossbeam 300, and the second end of the third column 5 is connected to the first fixed tube 302 of the second crossbeam 301. In this case, the crossbeam has a two-section telescopic structure. The arrangement of the third column 5 ensures that when the stand body 1 is in the expanded state, the distance from the third column 5 to the first column 400 is equal to the distance from the third column 5 to the second column 401.

[0036] When the user selects a three-section telescopic crossbeam, the crossbeam 3 includes two first movable tubes 303 and two third uprights 5 . The first end of one third upright 5 is connected to the first fixed tube 302 of the first crossbeam 300, and its second end is connected to the first fixed tube 302 of the second crossbeam 301. The first end of the other third upright 5 is connected to the first movable tube 303 of the first crossbeam 300, and its second end is connected to the first movable tube 303 of the second crossbeam 301. The arrangement of these two third uprights 5 divides the distance between the first and second uprights into three equal parts.

[0037] When the user selects a telescopic beam with four sections or more, the beam 3 includes multiple first movable tubes 303, and the number of third columns 5 is the same as the number of first movable tubes 303, wherein the first end of one third column 5 is connected to the first fixed tube 302 of the first beam 300, and the second end thereof is connected to the first fixed tube 302 of the second beam 301; the other third columns 5 correspond one-to-one to the first movable tubes 303 on the first beam 300 or the second beam 301, and the first end of each third column 5 is connected to the first movable tube 303 of the corresponding first beam 300, and the second end thereof is connected to the first movable tube 303 of the corresponding second beam 301.

[0038] The first end of the third column 5 is connected to the side wall of the first movable tube 303 of the first beam 300 away from the first fixed tube 302, and the second end of the third column 5 is connected to the side wall of the first movable tube 303 of the second beam 301 away from the first fixed tube 302; when the bracket body is in the folded state, the third column 5 is close to the second column 401.

[0039] The first linear drive mechanism, the second linear drive mechanism and the third linear drive mechanism all include a drive motor 7 and a screw 700 rotatably connected to the inner hole of the movable tube; the output end of the drive motor 7 is transmission-connected to the screw 700 for driving the screw 700 to rotate; a sliding seat 704 is threadedly connected to the screw 700, and the outer wall of the sliding seat 704 is connected to the inner wall of the movable tube; when the screw 700 rotates, the sliding seat 704 drives the movable tube to move synchronously.

[0040] There are at least two supporting legs 2, and a pulley 200 is connected to the bottom of each supporting leg 2; the supporting legs 2 are connected to the bottom of the second beam 301, and when the second beam 301 is expanded or closed, the supporting legs 2 move synchronously with the second beam 301.

[0041] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
